Specication o' Letters Patent.

Patented rune 1, 1909.

Application iled August l1, 1908. Serial No. 447,976.

To all whom it may concern.'

Be it known that l, JOHN l?. CRANE, a citizen of the United States of America, and resident of Springfield, in the county of Hampden and State of Massachusetts, have in vented certain new and useful Improvements in Sliver-Cans, of which the following is a full, clear, and exact description.

As well known, slivers or drawn cotton stock delivered from the carding machines and from the drawing rolls are run into cans having open tops, and there is a tendency, when a can is removed from its sliver receiving position under the guide plate appurtenant to the drawing machinery, for the sliver to expand and overflow at the top of the can,-a considerable portion thereof often falling from the can, and either becoming wasted in the mill or if reclaimed more or less soiled and deteriorated.

This invention consists in a can made with an upwardly extensible extension or annular' shell which may be slid when the can is being removed from its sliver receiving position to some other part of the mill, from its normal lower position to its raised, can elongating, position in an extent ample or corresponding to the amount that the sliver swells or bulges and for preventing overflow.

The invention furthermore comprises certain structural features and arrangements for utility and advantage hereinafter rendered more apparent.

In the drawings :-Figures l and 2 are substantially similar side elevations of the improved sliver can, with parts in section for clearer illustration, the first view showing the annular extension section as in its lowered or normal position, while such section is shown as upwardly extended in the second view. Fig. 3 is a side elevation of the upper portion of the can as seen at right angles to Fig. l. Fig. 4 is a similar view as seen at right angles to Fig. 2 3 Fig. 5 is a partial horizontal cross section as taken on line 5 5, Fig. 2, and viewed in the direction of the arrow.

ln the drawings, the dimensions of the Walls of the can proper and extension section are somewhat exaggerated in thickness for clearer illustration.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents the sliver can which may be of the usual cylindrical form and commonly having a diameter of about one foot and a height of three feet.

These cans in most cases are made of paper or indurated fiber and the strengthening rib or bead-like flange c surrounding the can mouth is retained as heretofore.

B represents the annular extension section, made in the form of a cylindrical shell or collar surrounding and frictionally fitting about the open upper portion of the can and adapted to be upwardly slid for elongating the latter.

As shown the annular extension has at its lower end an internal annular rib or beadlile lange l).

The can near its upper end is provided with either a single outwardly extending projection or stud d or duplicated and diametrically opposite studs, the same being connected with the can wall by riveting as shown.

f represents a vertical passage in the wall of the extension section in which said projection d is engaged, and by reason of which passage the extension section is free to be raised and lowered without impediment by the stud, although the upper end of the passage which is constituted by the shoulder g constitutes a means for limiting the downward movement of the annular section relatively to the can proper, and so that the said section is always retained in its position surrounding the upper end of the can. rlhe annular section B moreover has in a lower portion thereof a horizontal passage f 2 intersecting the vertical one f, the upper wall or boundary of which constitutes a shoulder so that the elevated extension section, upon being slightly rotated will have a supporting engagement, while in its elevated position, on the stud.

rlhe aforementioned angularly disposed and intersecting passages in the example of the structure here particularly shown are made in the form of grooves in the inner wall of the extension section, and so that a continuous, comparatively strong, and also sightly can extension is produced, with provision for even guidance of the movable p art relatively to the stationary one and for the exclusion of dirt, cotton or any obstructing mat-ter from the interengaging parts.

ln the manufacture of the sliver can with the annular extension section such extension is slid to its position embracing the mouth portion of the can from the can bottom and before the stud or studs (Z are riveted or otherwise affixed to the can; and for facilitating the connection of the stud with the can wall a comparatively small aperture i is provided entirely through the wall of the extension section coincident with the upper end of the groove as clearly shown in the drawings.

`While the object of my invention may bc attained by the provision of but one stud to the can and one angular passage f, f2 in the extension section, a duplication o'lE these provisions is generally to be preferred as giving a balanced and equalized guidance and engageinent for the slidable extension section at opposite sides of the device.

The improved appliances While adding very slightly to the cost of each sliver can greatly increase the practical value of the can in the mill, whore hundreds of the cans are constantly in use as enabling by the entirely convenient and quick manipulation of the extension section by the operative, a great saving in cotton stock which under present usage in mills is not made.

l claim:-

l. A sliver can, comprising in combination with a can, an annular sleeve loosely inclosing said can and having a bayonet-slot formed partially through its thickness on its interior, a pin located on said can and near its upper edge, and slidably engaging said bayonet slot, said sleeve being also provided with an opening in its side and entering said groove at a point over said pin whereby said pin may be inserted or removed to render said sleeve removable.

2. A sliver can com rising in combination and registering with said pin, whereby to aiford access thereto, for its removal or insertion.
